Alrighty...today is my A/C fix day. I plan to go with a propane route so I don't spend inordinate amounts of money with R134a for it only to leak out again.

I bought an A/C pressure gauge set and it held pressure for several hours....I topped it up with R134a and after about 2 weeks it leaks out.

If it is holding a vacuum it shouldn't leak out should it?

Any ideas? I also think propane will help me figure out where it is leaking too.
